With an urge to secure the WordPress website, I always seek the possible ways to find a vulnerability and remove it.
There are many website owners, who are struggling to understand the WordPress CMS(Content Management System). I remember when I used to freak out, but not anymore.
If you scan your WordPress admin panel, you may find an option to edit your WordPress theme's coding files, and so does for the plugins.
It's possible that hackers can inject some malicious code to these files and the website may never be as it is now. It's essential to stop such access directly to the coding files of your WordPress website through its admin area.
If you want to edit something, it's better to use cPanel.
Let me show you a screenshot to find the editing option. Login to your WordPress admin panel, go to Appearance>>Editor, this editor option is to modify your WordPress theme code.
For plugins, go to Plugins>>Editor. You can see an example of the code editor below.
In this tutorial, you're going to learn about removing these editors from the WordPress dashboard, so that even if someone hacks your website by brute force attack, they can't mess up with the coding files.

The .htaccess and wp-config.php are the two most vital files of a WordPress site. In most of the cases, whenever you require to add or improve any functionality, you ought to use these files.
To remove the file editing option from the WordPress admin panel, you must use the wp-config.php file; I hope you know how to locate it.

Even if you host multiple websites on your single web hosting server, you can easily find their core files and folders. Depending on the web hosting company you have, without getting confused with the design of cPanel, you should try finding the file manager and open it.
Make sure you open the public_html directory, make people also call it a root directory.
Search for the wp-config.php file by scrolling down and right-click to edit. You can also choose an Edit option from the main navigation menu of cPanel.
Click Edit; a new tab opens in the browser.
You can see a bunch of coding lines. Well, no need to be scared,
define( 'DISALLOW_FILE_EDIT', true );
Click Save Changes from the top-right corner of the screen to save the file.
Now login again to the admin panel of your website and check if you see the Editor option for themes and plugins. If not, you have successfully disabled the file editing from WordPress dashboard.

So why not take the initiative to remove the editor? I hope you can easily accomplish such a task.
